in thread Parse string and extract word after specific pattern

It also avoids the result, though.

my $s = 'a.b.c'; say "1: $_" for split /\./, $s; say "2: $_" for split '.', $s;
($q=q:Sq=~/;[c](.)(.)/;chr(-||-|5+lengthSq)`"S|oS2"`map{chr |+ord }map{substrSq`S_+|`|}3E|-|`7**2-3:)=~y+S|`+$1,++print+eval$q,q,a,

    Apparently, the first argument to split is always treated as a regex, because split '\.', $s worked.

    The documentation implies a string and a regex are treated differently:

    (such as ' ' or "\x20" , but not e.g. / / )

    Seems that, as luck would have it, I never happened to use a regex meta character split 'x'.

    In light of the described differences in handling of ' ' vs / /, the documentation should state that the first argument is always treated as a regex even supplied as a string.

      > the documentation should state that the first argument is always treated as a regex

      It does at the very beginning of split:

      split /PATTERN/,EXPR,LIMIT split /PATTERN/,EXPR split /PATTERN/ split

      There are only three exceptions, space, empty regex, and /^/ .

      ($q=q:Sq=~/;[c](.)(.)/;chr(-||-|5+lengthSq)`"S|oS2"`map{chr |+ord }map{substrSq`S_+|`|}3E|-|`7**2-3:)=~y+S|`+$1,++print+eval$q,q,a,
